Oh, hello. You've caught me cleaning up.

0:00:580:01:01

I'm just changing the bin bag and, pooey, is it stinky!

0:01:010:01:06

Oh, I'm glad that is over.

0:01:060:01:09

BEEP!

0:01:090:01:11

I hear a beep, I see a flash.

0:01:110:01:13

I wonder what they're going to ask.

0:01:130:01:16

ALL: Hi, Nina.

0:01:180:01:21

-Hi, guys.

-We've got a question for you.

0:01:210:01:24

Why do flowers smell so nice?

0:01:240:01:26

That's a great question. Why do flowers smell so nice?

0:01:260:01:30

Flowers look lovely. I've never thought about why they smell nice.

0:01:300:01:35

Come to my lab and we'll do some experiments.

0:01:350:01:38

ALL: See you soon, Nina. Bye.

0:01:380:01:41

Bye!

0:01:410:01:42

I'll need some help to answer this one, and I know who to ask.

0:01:420:01:46

OK, Neurons. Time to get to work.

0:01:460:01:49

ALL: Neurons at the ready, Nina.

0:02:050:02:08

OK, today's question is, why do flowers smell so nice?

0:02:080:02:12

Which Neuron will be most useful in helping us find out?

0:02:120:02:15

-Me!

-Me!

-Me!

-Me!

-Me!

0:02:150:02:17

Will it be fabulous Felix?

0:02:170:02:20

I can help so very much, if you need the sense of touch.

0:02:200:02:24

Will it be beautiful Belle?

0:02:240:02:26

I send messages to brain from ear. If there's a sound, I'll help you hear.

0:02:260:02:31

Will it be lovely Luke?

0:02:310:02:32

For looking and seeing, day or night,

0:02:320:02:35

I'll help you with your sense of sight.

0:02:350:02:38

Will it be awesome Ollie?

0:02:380:02:39

If it's pongy or whiffy but you can't tell,

0:02:390:02:42

-I will help your sense of smell.

-Or will it be baby Bud?

0:02:420:02:46

Sour, salty, bitter or sweet, I'm your taste buddy whenever you eat.

0:02:460:02:51

BEEPING

0:02:510:02:53

It's Ollie!

0:02:550:02:57

-ALL:

-Go, Ollie! Go, Ollie!

0:02:570:03:00

Go, Ollie! Go, Ollie!

0:03:000:03:01

Go, Ollie! Go, Ollie!

0:03:010:03:04

-Go, Ollie!

-Standing by to smell and tell, Nina.

0:03:040:03:09

Today's question is, why do flowers smell so nice?

0:03:090:03:12

We'll definitely use our sense of smell for this. Ollie will help.

0:03:120:03:17

Right, I need to get the lab ready before the experimeters arrive.

0:03:170:03:21

Henry likes climbing. His sister, Rosie, loves horseriding.

0:03:230:03:27

Nicola likes ice skating. They all want to know why flowers smell nice.

0:03:270:03:32

Today, for one day only, Henry, Rosy and Nicola become the experimenters.

0:03:320:03:37

ALL: Hi, Nina.

0:03:390:03:40

Welcome to my science lab. Come in!

0:03:400:03:43

It's lovely to see you.

0:03:430:03:45

So, your question is, why do flowers smell so nice?

0:03:450:03:49

Why do you want to know that?

0:03:490:03:51

Because when my mum puts flowers in the vase, they smell nice.

0:03:510:03:55

And we want to know why.

0:03:550:03:57

I love it when flowers are in my lab.

0:03:570:04:00

They help take away the nasty smells from some of my experiments.

0:04:000:04:05

We need to investigate. For our first experiment,

0:04:050:04:08

-we're going to use our senses.

-ALL: Woo! A senses experiment.

0:04:080:04:13

We're ready, Nina!

0:04:130:04:14

OK, experimenters. Get those noses working.

0:04:140:04:18

I'm going to pass round this flower.

0:04:180:04:21

Have a good smell.

0:04:210:04:23

The roses have a lovely perfumey smell.

0:04:230:04:26

OK. Why don't you have a good sniff of all the other flowers?

0:04:260:04:31

-So, what does this flower smell like?

-Nothing.

0:04:340:04:38

Of nothing? Let me have a smell.

0:04:380:04:40

This flower doesn't have much scent at all.

0:04:410:04:44

-Perfume.

-Like perfume?

0:04:470:04:49

-I don't smell anything from this one.

-Neither do I.

0:04:530:04:57

-Ooh, what does that flower smell like?

-Horrible!

0:05:010:05:06

It's horrible! This senses experiment has shown us

0:05:060:05:09

that not all flowers smell nice.

0:05:090:05:12

For this experiment, we're all wearing our safety goggles.

0:05:130:05:18

Yes, it's very important to protect our eyes

0:05:180:05:21

when we're doing experiments in Nina's science lab.

0:05:210:05:25

And I'll protect my hands as I'll be using chemicals.

0:05:250:05:29

OK. In these test tubes are different chemicals.

0:05:290:05:34

Some chemicals can harm us if we breathe them in

0:05:340:05:38

or if we put our nose close to them. I'll waft the smell towards you.

0:05:380:05:42

Ooh, whiffy. They don't smell very nice.

0:05:440:05:48

-Oh, is it not very nice?

-No.

0:05:480:05:51

OK, well going to mix these two together...

0:05:510:05:54

..in this test tube.

0:05:560:06:00

I'm very carefully going to put this test tube into some hot water

0:06:070:06:12

to heat up the chemicals.

0:06:120:06:14

So, our test tube has cooled down after its hot bath.

0:06:170:06:21

I'm going to add one more chemical to make it safe to smell.

0:06:210:06:25

OK, guys.

0:06:270:06:29

What can you smell now?

0:06:290:06:31

Apples.

0:06:320:06:34

Apples, yeah?

0:06:340:06:36

You're right, apples. Ha ha!

0:06:360:06:38

So, I took different chemicals that didn't smell very nice

0:06:380:06:42

and, by mixing them together, made a lovely appley smell.

0:06:420:06:46

-It's like smelly magic!

-It's the magic of science, Ollie.

0:06:460:06:51

So, this experiment has shown us that smells can be made

0:06:510:06:55

by mixing different things together.

0:06:550:06:57

Flowers mix things together to make their smells too.

0:06:570:07:01

But to find out why flowers smell,

0:07:010:07:03

we're going to visit some special friends in the garden.

0:07:030:07:08

Off we go for another adventure.

0:07:130:07:15

Nina said she's taking us to meet some friends in the garden.

0:07:150:07:20

-I have a feeling it might be birds.

-Yeah! It might be big, black crows.

0:07:200:07:26

Listen. I think we're here!

0:07:260:07:28

Don't we look great? These are special beekeeper outfits

0:07:500:07:54

to keep us safe.

0:07:540:07:55

The friends I want you to meet in this lovely flower garden

0:07:550:07:59

are some very busy bees. So, follow me!

0:07:590:08:02

-Hi, Vince.

-Hi, Nina.

-Our beekeeper Vince is trained to look after bees.

0:08:210:08:27

Bees can sting, so you should always be very careful around them.

0:08:270:08:31

What an amazing sight! All those busy bees hard at work.

0:08:310:08:37

Now, this is called a beehive. Bees live in here

0:08:370:08:40

and their job is to make honey.

0:08:400:08:44

Did Nina say honey?! Oh, I LOVE eating honey!

0:08:440:08:48

It's so sweet and runny and... yum, yum, yummy!

0:08:480:08:53

The bees that we can see buzzing around the garden are collect nectar

0:08:530:08:57

from the inside of the flowers.

0:08:570:09:00

Nectar is a sugary, sweet liquid that some plants make

0:09:000:09:04

and the bees bring it back here to the beehive to make it into honey.

0:09:040:09:09

But how do think the bees find the flowers?

0:09:090:09:12

-Do they see the bright colours?

-Bees have a good sense of sight,

0:09:120:09:16

but they also have a very good sense of smell.

0:09:160:09:19

the flowers create special smells to attract bees and other insects

0:09:190:09:25

so that they come and collect their nectar. But how do the flowers make

0:09:250:09:29

so many different, lovely smells? We need to go back to the lab!

0:09:290:09:34

We're going to make our very own smells, just like flowers.

0:09:360:09:41

All these bottles have different perfume oils in them.

0:09:410:09:46

We're going to have a good smell and choose our three favourite scents.

0:09:460:09:51

Let's get sniffing!

0:09:510:09:53

They all smell very different, don't they?

0:10:040:10:07

-Yeah.

-All these perfume oils come from plants and flowers,

0:10:070:10:12

so a rose oil comes from roses! Have you picked your three favourites?

0:10:120:10:18

-Yes.

-OK. We're going to put one drop of each of our chosen perfume scents

0:10:180:10:23

into the test tube and add a little water.

0:10:230:10:27

Well done, guys, we've all made our very own perfume! Let's sniff them.

0:10:470:10:53

Oh, here we go! It's a perfume sniff-athon!

0:10:550:10:59

What do yours smell like? Rosie?

0:11:020:11:06

-Minty orange.

-Minty and orange? Lovely! Henry, what's yours like?

0:11:060:11:11

-Em, orange.

-Do you like it?

-Yes.

0:11:110:11:16

-What's yours like, Nicola?

-It's sort of minty.

0:11:160:11:19

Lovely! You've done really well! Well, I'm afraid, guys...

0:11:190:11:23

mine's not very nice. I used some of the same oils that you guys did,

0:11:230:11:29

but my mixture's completely different and not very nice at all!

0:11:290:11:33

So this experiment has shown us that new and different smells can be made

0:11:330:11:38

by mixing other smells together, and that's what flowers do!

0:11:380:11:43

You asked, why do flowers smell so nice? And I think we've answered it!

0:11:470:11:52

First we found out that while some flowers smell nice, some don't.

0:11:520:11:58

We discovered that flowers give off a scent

0:11:580:12:01

to help bees and other insects find their nectar.

0:12:010:12:06

They take smelly chemicals from the soil and mix them to make smells.

0:12:060:12:10

By smelling different to other flowers,

0:12:100:12:13

they can attract the bees and other insects they need.

0:12:130:12:16

These insects then help them make more flowers.

0:12:160:12:20

-I hope that's answered your question.

-ALL: Thanks, Nina. Bye!

0:12:200:12:25

Bye!

0:12:250:12:28

If you want to know more about the science that's all around us

0:12:300:12:34

go to the Nina section on the CBeebies website. Have fun!

0:12:340:12:37

-Lab coat on, Nina?

-Lab coat on, Ollie.

0:12:410:12:44

-Safety gloves on, Nina?

-Safety gloves on, Felix.

0:12:440:12:48

-And don't forget your goggles, Nina.

-Goggles are on, Luke.

0:12:480:12:52

I think we're ready!

0:12:520:12:54

0:13:220:13:24

I really enjoyed myself today. A day of serious sniffing and smelling.

0:13:240:13:30

Ah, it's been such a great day, man!

0:13:300:13:33

So many colourful flowers to admire! Beautiful!

0:13:330:13:38

I've had a fabby day!

0:13:380:13:41

The best bit was meeting the honey bees! Bzzzzzz!

0:13:410:13:47

I've had a brilliant day!

0:13:470:13:49

It was so cool when everyone made perfume!

0:13:490:13:53

Our day's been bursting with sensational experiments!

0:13:530:13:57

-I hope you've enjoyed it! See you soon! Bye!

-Bye!

0:13:570:14:01

Scientist Nina and her young Experimenters discover the amazing ways that things can change and react in the everyday world.

Nina investigates why flowers smell so nice. Experimenters Henry, Rosie and Nicola visit Nina in her science lab and use their senses to discover that not all flowers do smell nice. Then they do an experiment to show that smells can be made by mixing things together, which is what flowers do.

Then they visit a beautiful garden and meet some very busy bees who collect nectar from flowers to make honey, and find out that flowers use their lovely smells to attract the bees. Finally, back in the lab, they discover that by mixing smells together you can come up with a new, different smell which helps the flowers attract the bees and insects who help them make more flowers.
